Construction of an Escherichia coli-Clostridium perfringens shuttle vector and plasmid transformation of Clostridium perfringens.
A stable shuttle vector which replicates in Escherichia coli and Clostridium perfringens was constructed by ligating a 3.6-kilobase (kb) fragment of plasmid pBR322 with C. perfringens plasmid pHB101 (3.1 kb). The marker for this shuttle plasmid originated from the 1.3-kb chloramphenicol resistance gene of plasmid pHR106. The resulting shuttle vector, designated pAK201, is 8 kb in size and codes...
متن کاملStable Escherichia coli-Clostridium acetobutylicum shuttle vector for secretion of murine tumor necrosis factor alpha.
Recombinant plasmids were constructed to secrete mouse tumor necrosis factor alpha (mTNF-alpha) from Clostridium acetobutylicum. The shuttle plasmids contained the clostridial endo-beta1, 4-glucanase (eglA) promoter and signal sequence that was fused in frame to the mTNF-alpha cDNA. The construction was first tested in Escherichia coli and then introduced in C. acetobutylicum DSM792 by electrop...
متن کاملConstruction of a new Streptococcus pneumoniae-Escherichia coli shuttle vector based on the replicon of an indigenous pneumococcal cryptic plasmid.
The nucleotide sequence of a cryptic plasmid (pRMG1) isolated from a type 1 Streptococcus pneumoniae has been determined and two recombinant plasmids, pRMGE1 and pRMGE2, bearing the pRMG1 replicon have been constructed. pRMGE2 is a shuttle vector for Escherichia coli and S. pneumoniae. The important characteristics of this cloning vector are: a size of 5.5 kb including a 1.4 kb fragment of pRMG...
متن کاملShuttle plasmids for Escherichia coli and Clostridium perfringens.
Small plasmids which replicate in both Escherichia coli and Clostridium perfringens were made by recombining E. coli plasmid pBR322 with three different small (less than 4 kilobases) plasmids native to C. perfringens. Subsequently, two homologous, though distinct, tetracycline resistance determinants (tet) from other C. perfringens plasmids were cloned into them. Both tet systems made E. coli r...
متن کاملConstruction of a Shuttle Vector for Heterologous Gene Expression in Escherichia coli and Microalgae Anabaena
The construction of an integrative shuttle expression vector and potential utility was reported in Escherichia coli and Anabaena (Nostoc) sp. strain PCC 7120. The vector comprised of the following elements: (a) an intergenic non-coding region from Anabaena to facilitate its genomic integration (b) a strong functional PpsbAI promoter from Anabaena for desired gene expression and (c) neomycin pho...
